Previews that are right on sites that render themselves.

One call, no signup POST /v1/metadata → application/json

Anonymous calls run at 40 an hour against your address. A free key raises that and works from anywhere.

# No key needed. Try it on a site that renders itself — the og: tags
# a plain fetch sees there are the shell's, identical on every URL.
